Sure, if one chooses to use sp to define such, but one defines in terms of an em-square (the utility of the sp is that it forecloses on rounding issues).

You're not going to have a useful value of less than a dot on an imagesetter though, so 1/3600th of an inch is as small as it goes and 1/2400 or 1/2540 is more typical, and w/ a graver one can take a curl off of a steel punch which is that thickness or smaller, see Fred Smeijers, _Counterpunch: making type in the sixteenth century, designing typefaces now_.
